Using Clay Molds For Fondant/gumpaste???

I was in Michael's in the clay/sculpting section and came across some plastic molds used for making doll faces. Has anyone ever used these for fondant/gumpaste? Do you think they would work? I didn't buy them, but considering it....

Absolutely go ahead and make the purchase! Simply dust the mold with a little corn starch so it releases well, and use a 40/60 combo of fondant to gumpaste. If molding faces, etc., I don't think they ever come out quite the same as the mold, but I really wouldn't want them to. The mold is a great "starting point" for the face from which you individualize from there out. Hobby Lobby has them as well... don't forget to use your coupons!
